Overview

We present a case study of a 47-year-old woman with cholecystolithiasis, in whom a diagnostic examination showed a solid-cystic lesion in the subhepatic region, oppressing the biliary tract. After completing examinations with imaging techniques (ultrasound, CT, MR) and endoscopic retrograde cholangiopancreatography (ERCP) with biliary drainage through a duodeno-biliary stent, the patient was directly indicated for a resection. Mucinous neoplasia of the biliary tract or cystic anomalies were considered as possible diagnoses prior to the surgery. The lesion was resected together with the adjacent gallbladder and biliary ducts. Surprisingly, the histological examination of the resected tissue showed a non-tumorous affection – adenomyomatosis of extrahepatic biliary ducts.
